Final answer:
The first stage in Rogers' Diffusion of Innovation Theory is Knowledge or Awareness, where the individual is first exposed to an innovation.
Step-by-step explanation:
In Rogers' Diffusion of Innovation Theory, the stages of individual change begin with the first stage, known as Knowledge or Awareness. This initial stage is when an individual is first exposed to an innovation but lacks information about it. Here the individual has not yet been inspired to find out more about the innovation and is not contemplating its use.
The subsequent stages following this initial awareness are Persuasion, Decision, Implementation, and Confirmation. These stages collectively describe how a new idea, product, or practice spreads within a society or among groups within that society, from initial knowledge to full-scale adoption, potentially leading to a market share of 100 percent, or complete saturation.
